Xiao,

 i tried your perf events patch set on RHEL 6.1 host and failed to trace kvm-events with below error message.

  [root@kvm perf]# ./perf kvm-events report
  Warning: unknown op '{'
  Warning: Error: expected type 5 but read 1
  Warning: failed to read event print fmt for hrtimer_start
  Warning: unknown op '{'
  Warning: Error: expected type 5 but read 1
  Warning: failed to read event print fmt for hrtimer_expire_entry
  Analyze events for all VCPUs:
  VM-EXIT    Samples  Samples%     Time%         Avg time               
  Total Samples:0, Total events handled time:0.00us.
  [root@kvm perf]#
